GFS_PIO_DATASYNC(3)

✨ NAME ✨

gfs_pio_datasync — bestie, this one dumps your file's data out of memory and onto the disk, fr fr 💾✨

🌸 SYNOPSIS 🌸

#include <gfarm/gfarm.h>

gfarm_error_t gfs_pio_datasync(GFS_File gf);

💅 DESCRIPTION 💅

okay so. gfs_pio_datasync flushes all that data just vibing in memory for your gf, and then it waits — like, actually waits — for the I/O to finish before it comes back to you. no rushing, no "yeah sure it's done", it's giving patient main character energy 🫶

the one thing it does not do is update the metadata stat info. nope, not its job. if you want the metadata updated too, that's a whole different function: gfs_pio_sync, which handles the metadata on top of the contents. so like, gfs_pio_datasync = data only, gfs_pio_sync = data + metadata. iykyk 💅

🌈 RETURN VALUES 🌈

• GFARM_ERR_NO_ERROR — it ate and left no crumbs. the function terminated successfully ✨
• GFARM_ERR_NO_MEMORY — not enough memory was available 😭 tragic, honestly
• Others — some other error happened that isn't either of the above. the reason gets shown by gfarm_error_string(3), so go check that 👑
